The: objectof this invention isto provide an inexpensive, dependable and eflioient. robberyproof' apparatus. which can read ly "b at tached to cashiers cages, teller windows and "1 the like,w-hich cannot injure a persons hand.

115 holdup. We attain these Objects by the mechline L- 5 looking from anism illustrated in the accompanying drawings,'in whichz' "Fig. 1 is a view of the apparatus shown as attached on the inside ofa cashiers window, showing bullet-proof steel, plate 3, held up by means of lock 14, and compressing springs 7. v

Fig. 2' shows device, after it has. been tripped, and 3. and 2, are shown completely closing the window with bulletrproof steel late.

P Fig. 3 is'a sectional view along the line 3-3, looking from A to B. V

Fig. 4 is a view looking from right to left along the line 4-4.

Fig. 5 is apart sectional view along the C to I r Fig. 6 is a part sectional view showing lock and solenoid control.

Similar numerals refer to similar parts throughout the different views.

The bullet-proof steel plate 3, is fitted into longitudinal grooves 24, arranged in frame parts 6. This steel plate slides up and down in the same manner as does a double-hung window without weights. 7

When 3, is lifted manually to the top of the longitudinal grooves, in frame parts 6, it will compress the springs 7, and latch by means of and 14, which are controlled by solenoid 10. Then, if one of the switches 11, be closed, the battery will magnetise solenoid 10, which in turn will draw 14 from 15, and 3 will fall to position shown in Fig. 2, springs 7, serving merely to increase the speed of the downward motion of the bullet-proof steel plate 3. In order to prevent in ury to the hands in case they should be directly beneath 3,'when it falls, we have provided a I1162111Si0 stop 3 at such height that it would be above any persons hand right beneath, preferably one and one half inch or two inches, at which time the steel plate 3, comes in contact with 17 (Fig. pushing it downward, which in turn operates 18, compressing spring 25, and releasing pin 22, which serves as a inch for holding sub-plate 2, in a horizontal position as shown in Fig. 4, also serving again as a lock when 2 is brought up to a vertical position, 19 falling behind it, thereby locking 2 in an upright position,-as can be seen in Fig. 4, the spring 20 is hooked at one end around 22 and dowe.ed into frame part 6 at the other end. Said spring being coiled around 21, which is a cylindrical extension of 2. The spring20, tends to lift 2, to a vertical position, and must be forced down to the horizontal position manually, and is held in that posit-ion by 18. It can readily be seen that when the plate 3, falls, sub-plate 2, will be released and will rise only by the strength of the spring 20, which is not strong enough but that the weight of ahand would hold it down even though it were tripped.

Obviously, the present invention is not restricted to the particular embodiment thereof, herein shown and described. 1 Moreover, it is not indispensable that all the features of the invention be used conjointly, since they maybe employed advantageously in various combinations and subcombinations'.

We, claim 1. A robbery-proof apparatus ofthe class 2. A safety device of the class described,

comprising in combination, a bullet-proof steel main plate, said steel main plate being mounted within channels or grooves; and means for controlling said main plate from any desired location; and a sub-plate operated by a spring and released by said main plate, after it has been stopped at the end of its travel, said sub-plate closing the opening left bysaid main plate.

3. A robbery proof apparatus, comprising in combination, a bullet proof steel plate, movably mounted in channels or grooves, and a latch to hold said bullet proof steel plate at the top of its channels; and a sub-plate, suitably located between the bottom of said Chan-t nels, adapted to swing on a horizontal pivot into the plane of the sliding bullet proof steel plate to complete the closure; and a spring normally to swing said sub-plate on its horizontal pivot into the plane of the sliding bullet proof steel plate; and a lock normally to hold said horizontal plate in a reclining position; and a sliding rod actuated by said sliding steel plate to release said lock holding steel horizontal plate in a reclining position; and another lock adapted to hold said horizontal plate in the plane of the sliding bullet proof steel plate.

l. A robbery proof apparatus comprising in combination, a sliding steel plate vertically mounted in channels; a steel sub-plate at the bottom of said channels adapted to swing on a horizontal pivot into the plane of said sliding steel plate; and means for holding said sliding steel plate at the upper end of said channels; and means for holding said steel sub-plate in a reclining position; and means for lifting said steel sub-plate on a horizontal pivot into the plane of said sliding steel plate; and means for releasing said sliding steel plate, allowing it to fall sliding in the channels; and means for locking said steel sub-plate in the plane of said steel sliding plate completing the closure; and means for locking said sliding steel plate at the bottom of the channels.

5. A robbery proof apparatus, comprising in combination, a channeled frame, adapted to be secured in a vertical position to a window or cashiers cage; a main plate adapted to slide within the channels of said frame; a sub-plate suitably mounted at the bottom of said frame, and adapted to swing on a horizontal pivot into the plane of the main plate, said channels ending at a point above the bottom of the frame, stopping said main plate in its downward travel, so that said main plate conjoins with said sub-plate, when said sub-plate is in the plane of said main plate; spring means for lifting said subplate from a reclining position into the plane of said main plate; a lock for holding said sub-plate in a reclining position, and means actuated by said main plate for releasing said look; and another look for holding said subplate in the plane of said main plate; and also a lock for holding said main plate at the bottom of its travel; and a latch for holding said main plate at the top of the channels in said frame; and means for releasing said latch.

6. A robbery proof apparatus, comprising in combination, a channeled frame adapted to be secured in a vertical position to a window or cashiers cage; a mainplate adapted to slide within the channels of said-frame; and spring means to actuate said main plate; a sub-plate suitably mounted at the bottom of said frame, and adapted to swing on a horizontal pivot into the plane of the main plate, said channels ending at a point above the bottom of the frame, stopping said main plate in its downward travel so that said main plate conjoins with said sub-plate when said sub-plate is in the plane of said main plate; spring means for lifting said subplate from a reclining position into the plane of said main plate; a lock for holding said sub-plate in a reclining position; and means actuated by said main plate for releasing said lock; and another look for holding said subplate in the plane of said main plate; and also a lock for holding said main plate at the bottom of its travel; and a latch for holding said main plate at the top of the channels in said frame; and means for releasing said latch effecting a closure from any desired location in a building.

In testimony, we claim the foregoing as our own, we have hereto afiixed our signatures. PAUL F. WEST.
